It's always useful to know which third party power banks out there can work well with your Nintendo Switch just in case you need a power source when on the road. Here we find out if the BatPower PD6's Power Bank is able to supply USB Power Delivery charging to the Nintendo Switch Console on a 10% full battery and Joy-Con controllers connected. 

In order to connect the BatPower PD6 to the Nintendo Switch Console over USB Type-C, we use the BatPower USB Type-C Adapter between both devices. The Console is already running active gameplay using the attached left and right Joy-Con Controllers when it starts charging with the BatPower. We can see the BatPower declares that it can deliver 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps ), 36 watts (12 volts @ 3 amps), 45 watts (15 volts @ 3 amps) and 60 watts (20 volts @ 3 amps) over USB Power Delivery. Note this max 60W doesn't comply with the 90W advertised by the BatPower PD6, which also shares the same power profiles with its own AC Adapter as recently observed.

We also notice the Nintendo Switch Console requesting the same initial 7.5 watts (15 volts @ 0.5 amps) when charging with the BatPower PD6's AC Adapter. The BatPower PD6 then agrees to supply this 7.5W to the Console. 

The Console then follows up to finally settle on 45 watts (15 volts @ 3 amps) of charging with the BatPower, which was also seen with the BatPower's AC Adapter.

Starting from 10% battery charge, we can see that the Switch Console with Joy-Con controllers is able to pull current resulting in a 17 to 21.7 watts power band. The BatPower PD6 is able to charge the Nintendo Switch Console using similar power as well as the Nintendo Switch AC Adapter as seen in this review over USB Power Delivery.

Note that the BatPower PD6 takes more than 20 seconds to finally charge the Switch Console. We also did not observe the Console pulling anywhere near 3 amps as established during the USB Power Delivery negotiations.
